"""Convert CLDR data to qLocaleXML
The CLDR data can be downloaded from CLDR_, which has a sub-directory
for each version; you need the ``core.zip`` file for your version of
choice (typically the latest). This script has had updates to cope up
to v38.1; for later versions, we may need adaptations. Unpack the
downloaded ``core.zip`` and check it has a common/main/ sub-directory:
pass the path of that root of the download to this script as its first
command-line argument. Pass the name of the file in which to write
output as the second argument; either omit it or use '-' to select the
standard output. This file is the input needed by
``./qlocalexml2cpp.py``
When you update the CLDR data, be sure to also update
src/corelib/text/qt_attribution.json's entry for unicode-cldr. Check
this script's output for unknown language, territory or script messages;
if any can be resolved, use their entry in common/main/en.xml to
append new entries to enumdata.py's lists and update documentation in
src/corelib/text/qlocale.qdoc, adding the new entries in alphabetic
order.
While updating the locale data, check also for updates to MS-Win's
time zone names; see cldr2qtimezone.py for details.
